Best practices

Accessibility of mobile apps and sites

Touch targets, mobile screen readers, zoom: what changes on mobile and how to make it accessible.

A large share of traffic is mobile, and the EAA also covers apps. Mobile accessibility shares the web's principles, with a few specifics.

Touch targets

Buttons and links must be large enough and spaced enough to be activated with a finger without error. WCAG 2.2 strengthen this requirement.

Mobile screen readers

VoiceOver on iOS and TalkBack on Android read the interface. Components must be correctly labelled and their state announced, exactly as on the web.

Zoom and orientation

Content must remain usable when the user enlarges text or changes screen orientation. Disabling zoom is a frequent trap to avoid.

Test in real conditions

Beyond automated tests, trying your app with a mobile screen reader quickly reveals concrete obstacles.
